Noun: An older avuncular cadge that enjoys sponging off of relatives. Often shows up during meal time with the sole intent to mooch a free meal. Oblivious to the fact that his presence in one's household is an imposition to everyone else.
I would have had plenty of food left over for lunch tomorrow save for the fact that Uncle Swine showed up unannounced and ate with us.

The "fun uncle" is an inappropriate jest move that involves purposefully flipping one's manhood out of one's pants in front of others as if by accident to attempt to shock, awe, or make laugh.
When the teacher stepped out of class, I had to see Merlin's Schlong as he took the opportunity to give us all the Fun Uncle.

(n) A double uncle is man who is someone's mother's brother and also that person's father's brother. In other words, a double uncle is an uncle on both sides of the family. For a double uncle to exist, a child must be a product of incest between two siblings, and the parents must share a brother.
Tyrion Lannister from A Song of Ice and Fire / Game of Thrones is probably the most well known double uncle. His double nephews don't appreciate him like a double uncle should be appreciated.
Person A: Dude, Tyrion is freaking awesome. He's probably my favourite character at the moment.
Person B: Yeah, it's a shame he's that Joffrey faggot's double uncle.
-----
Person A: My double uncle said he'd get us all ice creams!
Person B: Double uncles are the greatest!
Double Uncle: Now get back in my van, kids. And don't scream.
